Transportable Building Sliding Strip Friction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportable buildings face challenges in assembly efficiency, limited height, sealing issues, and high frictional forces during expansion, which hinder easy and tool-free assembly and deployment.
Innovation Solution
The use of slide strips, particularly Teflon strips, between frame and floor elements reduces friction, allowing for manual assembly and easy deployment of foldable, pivotable, and displaceable elements, enabling a two-story structure with minimal effort and without the need for cranes or heavy machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If floor profile elements are inserted into frame profile elements for transport, then the building can be transported in a compact state, but high frictional forces arise when pulling out elements for assembly
Solution Approach 1:
A sliding strip is introduced as an intermediary element between the floor profile elements and frame profile elements. The sliding strip is attached to the inner surface of the frame profile element and contacts the outer surface of the floor profile element during insertion and withdrawal operations. This intermediary sliding strip reduces the frictional force between the metal profile elements, enabling easy manual assembly and disassembly without requiring excessive force.
2Ease of operation
If the building is assembled manually without tools, then assembly effort is reduced, but assembly precision and stability may be compromised
Solution Approach 1:
The sliding strip serves as a mediator that enables manual assembly while maintaining precision. By reducing friction between the profile elements, the sliding strip allows manual insertion and withdrawal operations to proceed smoothly without tool assistance, yet the guided interaction between the sliding strip and profile elements ensures proper alignment and positioning, thereby maintaining assembly precision without requiring powered tools.
3Volume of stationary object
If the building structure is extended to two stories, then living space increases, but the weight and complexity of the construction increases
Solution Approach 1:
The building is divided into modular floor profile elements and frame profile elements that can be independently manufactured and then assembled. Each floor unit includes integrated sliding strips and connection elements that allow the floors to be inserted into the frame structure in a standardized manner. This segmentation enables the construction of multi-story buildings by simply repeating the modular floor units, thereby increasing building volume without proportionally increasing construction complexity.
4Volume of moving object
If separately transported uprights and lattice girders are used, then the transport unit can be compact, but assembly requires cranes and heavy machinery
Solution Approach 1:
The frame profile elements and floor profile elements are merged into a single integrated transport unit that maintains compactness during transport. The sliding strips are pre-installed on the frame profile elements within the transport unit, creating a self-contained assembly where the floor elements can be directly inserted into the frame elements during assembly. This merging eliminates the need for separate transport of uprights and lattice girders, and the pre-installed sliding strips enable easy manual assembly without requiring cranes or heavy machinery.
